ATMP Na4, ATMP Tetrasodium


ATMP Na4 is actually the tetrasodium salt of ATMP. It can easily prevent scale development. Such as calcium carbonate inside the water system. ATMP Na4 is able to be applied in circulating a cool system. Just like in power plants, oil refinery plants and also oilfield refill water systems. ATMP tetrasodium features excellent synergistic effects together with some other chemicals in neutral and an acidic condition. No ammonia smell is let off.

In industrial production, we often use ATMP Na4 to deal with scale and water corrosion of equipment. The tetrasodium of ATMP is a practical and efficient chemical treatment method. And it is relatively simple to use.

First ATMP Na4 combines with the metallic substances contained in the water. And the metal ions that react with other substances to form scale are restricted. And calcium ions are prevented from being precipitated. When used on the spot, ATMP tetrasodium will also dissolve the scale that has been generated to the maximum extent. And it further reduces the sedimentation rate of the scale. ATMP Na4 also reduces the probability of scale formation.

In addition to the effect of scale inhibition, ATMP tetrasodium can also provide a certain sustained release of scale formation. Usually, ATMP Na4 will directly form a protective film on the metal surface. This protective film is more difficult to dissolve and hinders the oxidation reaction between the metal and the air, thereby protecting it.

ATMP Na4 is used together with other organophosphorus acid, polycarboxylic acid or salt to form organic alkaline agents, it is used in circulating cool water system for all water quality.

ATMP Na4 can improve corrosion inhibition efficiency. Make it suitable for more demanding and more extensive environments, as well as reduce the cost of pharmaceuticals.

It is advisable to follow the criteria for adding corrosion and scale inhibitors when adding ATMP tetrasodium. If the device with the addition of ATMP Na4 is installed incorrectly, it will result in a large amount of waste. It will also increase the cost of water treatment.

With the increase in the use of ATMP Na4 in the factory, the occurrence of improper use has occurred. The added device is to be installed at the inlet of the reagent, and the correct installation of the device makes it easier to add reagents.

Pay attention to the added amount when adding ATMP Na4. If you add too much, it will overflow. When using the scale inhibitor installation, check the correctness of the installation before adding it.
